FREQUENCY BANDS
| Frequency | Range | Tait Band | Configuration |
|---|---|---|---|
| VHF | 136-174MHz | B1 | Factory set to 15W (Max 30W* typical) |
| UHF | 400-470MHz | H5 | Factory set to 15W (Max 25W* typical) |
| 700/800MHz | 762-870MHz | K4 | Factory set to 15W (Max 25W* typical) |
*The output power of the transportable unit is reduced due to the duplexer loss. This improves the battery shift life. If the unit is operated in a high duty cycle environment, for example the trunking control channel, output power should be limited to 15W.
